Specification forming part of Letters Patent No. 126,389, dated May 7,1872.

Specification describing certain Improvements in Hubs for Wheels,invented by JACOB G. GARRETSON, of Marshland village, county ofRichmond, Staten Island, State of New York.

The object of my invention is to manufacture hubs for wheels, which areso constructed that the spokes inserted in the same can be tightened, ifthey should shrink or become loose, and placed and replaced in a moreconvenient and handy manner than herctobefore done.

Figure I is a plan view of a wheel axle-box and hub embodying myinvention. Fig. II is a longitudinal cut section of the same throughline as m, Fig. I.

A represents an axle-box, to the end of which, in front of the wheel, areceptacle, B, is formed for the purpose of covering the nut securingthe wheel on the axle, at'the same time forming a shoulder, a. A stripor guide, 1), runs from this shoulder along the box A. Acap, O,is placedover the axle-boxAagainst the shoulder a, and is provided with a groove,0, in which the strip or guide bis inserted, thereby preventing the cap(3 from becoming dislocated or twisted. Another cap, D, provided withsquare receptacles h h for receiving the spokes of the wheels, madewider at the bottom, so that the spokes will become dovetailed therein,and which are placed at equal distances apart, is then placed over theaxle-box A, and is also prevented from becoming twisted or dislocated byaid of the groove d and the strip 11. A metal ring, E, is

fastened to the cap D with the aid of the bolts and nuts f and g,inserted between the receptaclcs h h, said ring serving to fasten orhold firmly the dovetailed spokes. In the cap 0 is arecessfl, whichserves to receive the ring E and the bolts and nuts f and y. A thirdcap, F, in all respects like the cap D, is now placed over the axle-boxagainst cap D; and a fourth cap, H, in all respects like the cap 0, alsoplaced over the axle-box against cap F, serving to make the hubcomplete. Anut, G, placed on the axle-box, threaded for this purpose,can be removed at pleasure, so that access can be had to the interior ofthe hub, when required, in order to fasten, tighten, or place new spokestherein.

It will be readily understood that the receptacles h k can be placed indifferent positions, as may be found desirable-for instance, byextending them from one cap into the other, or by placing them indifferent relative positions to each other.

Having thus described my invention, I desire to claim The caps O, D, F,and H, with receptacles h h, grooves c c and d d, rings E E, andrecesses i i, in combination with the axle-box A with the receptacle B,shoulder a, strip b, and nut Gr, substantially as and for the purposehereinbefore set forth.
